Why Waterproofing Matters in Park City
The Southwest is dry most of the year, so waterproofing here is event-driven rather than continuous. Monsoon thunderstorms can drop more rain in 30 minutes than the area normally sees in a month. Most homes do not need a full interior drain system — but they do need exterior grading, downspout management, and a vapor barrier. Homes near washes or in flood plains need full waterproofing.
What a Park City Waterproofing System Should Include
- ✓Vapor barrier (10–12 mil sufficient — low humidity year-round)
- ✓Exterior French drain along uphill side of property if grading is unfavorable
- ✓Extended downspouts (10+ feet) — monsoon bursts overwhelm short ones
- ✓Sump pump only if home is in a documented flood plain or near a wash
- ✓Hard-piped drain to a daylight outlet (most Southwest soils drain well)
- ✓Pest exclusion at all foundation penetrations
Interior vs Exterior Drainage in Utah
Recommendation
Most Southwest homes do NOT need interior perimeter drains. Exterior grading and downspout extensions handle 90% of moisture events. Reserve full systems for flood plain homes or those near washes.
Sump Pump Sizing
Skip the sump pump unless you are in a flood plain or near a wash. The dry climate means the pump rarely runs and seal degrades from disuse. If you do install one, prioritize a model rated for dry-cycle operation.
What to Watch For in Utah
- !Avoid contractors who push full interior drainage systems for non-flood-plain homes — likely overselling
- !In expansive-soil areas, exterior trench drains can crack as soils heave — check soil report first
- !Verify discharge daylight outlet is not on a neighbor's property (legal issue in the Southwest)
